Question

if there are 2 blue, 5 yellow, and 3 white marbles in a bag, what is the white marbles in a bag what is the probability of pulling a blue marble from the bag

Answer 1

The probability of pulling a blue marble from the bag is;

`P_B=(1)/(5)=0.2`

Step-by-step explanation:

Given that there are 2 blue, 5 yellow, and 3 white marbles in a bag.

The total number of marbles in the bag is;

`n_t=2+5+3=10`

The probability of pulling a blue marble from the bag will be;

`P_B=\frac{\text{ number of blue marble}}{\text{total number of marble}}`

Substituting the given values;

`\begin{gathered} P_B=\frac{\text{ number of blue marble}}{\text{total number of marble}}=(2)/(10) \\ P_B=(1)/(5)=0.2 \end{gathered}`

Therefore, the probability of pulling a blue marble from the bag is;

`P_B=(1)/(5)=0.2`
